I ingforpumpsn", q The purpose of. the present invention is to v provide means for conveniently attaching a pump to a gun when'replenishing hydroe w ne'umatic recoilmechanisms with'o' l. As

' the normal pressure within the recoil chamher is considerable, the filling device for greater unit pressure, consequently, it has c and a separate bracket either permanently orremovably attached to some part of the v gun is provided to securelyhold the filler Whenin operation. j 1

Accordingly, itis proposed to removably ;mount the pump on a convenient and access 7 .siblemember of the gunwithout the aid of I brackets or other independent supporting means and to provide a flexible hose for 35 "connecting the pump to the recoil chamber. To thesejand other ends, my invention [consists in the construction,arrangement, l vand combination of elements, described @forming a part of this's'pecification. 1'? A pr'acticalembodiment ofmyinvention illustrated in theaccompanying drawing, 'in Which, I f 5 g ;fFig l is a view in side elevation of the rear end of agun, showing the pump mount ed for operation; and r t V Fig. 2 is a sectional view onthe line 2-2 of Fig. 1. v i 1 Referring to the drawing by numerals or" reference: 7 v

According to the invention, a gun barrel v 11 is reciprocally mounted .on' a cradle12 g V I chamber 13. Mounted as MAN, a citizen of the United States, anda 'bi-bia, have, invented an Improvement ,in
